Your dog had babies? This might seem like a dumb question however...Ever since I got Heidi, her skin around her nipples has seemed really saggy. Could this be from having a few litters of pups? The story I got from the shelter was that Heidi had been given up because her "little old lady" was moving to a nursing home in CT and her son could not take care of her. From the day I brought her home there were definate signs of abuse. She was very submissive around Andrew, wouldn't eat if he was in the same room, peed if he came near her to pet her, and if he stretched or his arms or hands were raised would cower or run. She to this day is terrified of the vacuum cleaner. I know most dogs don't like them b/c of the high pitch noise they can make and often bark at them, but she full out attacks it if she is not in her crate. Her lower left lip is deformed and sags a little...I think someone got her with a vacuum (my mother is a nurse and she said the way the droop is she could have been abused w/ the attachment and her lip got sucked into it). I know she has had a rough life before me, and I am so thankful that I found her and brought her into my home. She will never have to worry about that again. Andrew was the one who pointed her belly out to me, and I have always kind of wondered if it was a sign of having given birth or not. I've really only had male dogs, had two females for a very short period of time so I don't know much about what happens when they are pregnant and give birth. Andrew thought that since her belly skin was all stretched out and droopy she had multiple litters...just curious if anyone knows anything about that.
